T all who-m itmay concern:

Be it known that I, STACY B. Ii-Insan- TINE, a citizen of the United States, residlng at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in 'Draft-Rigg1ng for Railway-Cars, of which the following 1s a time, reference being had to the accompanying draw forming a part of this SPGCIfiCatIOIL y invention relates to improvements in draft ri ging for railway cars.

The oliject of m invention is to provide a draft rigging of igh cushioning capacity.

In the'drawings orming a part of this ..specification-Figure 1 is a side elevation partly in longitudinal section on line 1-1 of Fig. 2 of adraft rigging embodymg my invention; Fig. 2 is a plan view partly 1n horizontal section on line 2 -2 of Fig. 1, and showing the normal position of the parts; Fig. 3isa plan view partly in horizontal section showing the position of. the parts when fully verse section on line side of the same, however, showing the compressed; Fig. 4 is a-transspring cap removed; Fig. 5 ma plan view partly in horizontal section showing the position of the parts when fully compressed in draft.

Referring to the drawings 6, 6 represent draft sills or parts of the car frame to which the draft rigging is applied, the same being provided with rear stop shoulders 7, 7 intermediate stop shoulders 8, 8 and front stop shoulders'9, 9.

'10 represents the end sill, 11 the draw bar carry iron, 13 the tie plate suitably secured to the draft sills, 14, 14, 15 the draw bar, 16 the draft yoke secured thereto, 17 the draft gear mounted within the yoke.

The inner shell 18 of the draft gear is preferably cylindrical in shape or circular in cross section, open atits forward end and v closed at its rear end by the preferably in tegral plate 19. Laterally extended from the rear end of said shell are plates 20, 20, the same being preferably continuations of the plate 19 and integral therewith, the same serving as a rear follower andadapted to engage the rear stop members 7',

Within the inner shell isdisposed friction mechanism 21, the friction shoes 22, 22

thereof being preferably three in number Specification of Letters Patent.

and annularly arranged, each having an outer friction face 23 to engage the internal friction face 24 of the inner shell. 'A wedge 25 is mounted within the adapted to spread the same, the said wedge bein provided with wedging faces 26, 26

friction shoes "and; 7,;

equa ing in number the -friction shoes. Be- 1" tween each wedging face 26 of thejwed g 25 and each ofthe friction shoes there is vided an a-ntifriction roller 27. The Wedge 25 is forwardly provided with receive the head 29 of the 30 which passes through the perforation31 in said Wedge, in the internal follower 33, the said follower being receive the nut 35 of said connecting rod."

The internal follower 33 is a block like internal pro- 6 a recess 28 to "1 connecting rod and through a perforation 32 J0 provided with a reoss34to member forwardly provided with a .fOi aJ-IQ wardly extending flange or collar 36 within which is mounted a preliminary spring'BT of low. capacity in comparison wlth springs of the draft gear hereinafter de scribed. The internal follower 33 is vided with a transverse slot 38 to receive the other the key 39, which extends through the elon' gated slots40 provided in either side'of the" inner shell 18. An the inner shell 18, the said outer shell being provided at either side with the slots 42:

key 39 therein.

The outer shell 41 is forwardly provided with the lateral wings 43, the same being outer shell 41 surrounds I at registering with the slots40 of the inner shell, and adapted to receive the ends of the.

preferably integral with the said shell,-be-

tween' which wings and the plates 20, 20 of the inner shell are seated wlthout the shell and at either side thereof the main springs 44. The main springs 44 each preferably consists of an outer spring 45 and an inner spring 46 nested therein. The wings 43 of l the outer shell are in normal position of the gear slightly removed from the intermediate stop shoulders 8, 8 the space between them in such normal posi the numerals 47 47 ings. The slots 40 reciprocatingmovement o the key 39 thereion being indicated by iniFig. 2 of th'e'drawprovided in the inner shell are of suilicientwlen h to permit the m. 48represents, the front ifollower adapt" ed to engage the. front stop shoulders 9', 9,

and

wedge 25 of the friction mechanism.

On rearward movement of the draw bar the in engagement at its rear face with the inner shell stopped 'agaihst rearward movement through the engagement of the plates 20 against the rear stop shoulders 7, 7.

The -rearwardtravel of .the front follower 48 forces the wedge 25fan'jd the friction shoes rea'rwardly, compressing the preliminary spring against the internal follower 233 until the collarBG of the internal'follower 33 engages the friction shoes-thus limiting the compression of the .lower33 moves rearw'ardly within the inner shell 18, the key 39 therein sliding rearwardly' in the lateral slots 40, 40 of the inner shell, and drawing the outer shell rearf wardly, thuscompressing the main springs between the wings 43 of the outer shell and theplate ZO ofthe inner shell. Meanwhile the spreading action of the wedge within the 20 friction shoes forces the friction shoes into ,frictiona'l engagement with the innervshell.

On full compression of the parts the front follower 48 engages the forward end of the innershell, as illustrated in. Fig. 3 of the drawings, and the key 39 clears the rear ends of the slots 40 in the inner shell.

forward movement of the draw bar the draft yoke draws the inner shell for- 7 wardly, the pressure of the main springs between the wings 43 of the outer shell the, internal follower remaining stationary, i

the slots 40 in'the inner shell moving forwardly without strain upon the said .key

' 39. The inner shell by reason of the slight pressure exerted against the rear ends of the'friction sho'e's travels forwardly about said.- shoes without the same being brought into compression resisting action on said for ward movement of the draw bar. Thus on forward movement of the draw bar the springs alone are in compression resisting action, while'in rearward movement'of the draw bar the springs and friction mecha- 'nism' are both-in action.
